SPIKE.

Butte, in the county of Silver Bow and State of Montana, have inventedcertain new and useful Improvements in Spikes; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same. v

This invention relates to certain new and useful improvements in a spikeand has for its primary object the provision of a spike speciallyadapted for use as a railway spike and constructed in such manner thatthe anchor pin will securely lock the spike in its innermost positionwithin the tie to hold .the rail securely in position and at the sametime may be bent so as to permit ready engagement of a tool with thehead thereof to withdraw the anchor pin when it is necessary to removethe spike.

Another object of the invention resides'in the provision of a spike-inwhich the anchor pin will be received in a groove in upper portion ofthe outer or rear side of the spike in such a manner that the beveledpoint of the anchor pin will be properly directed away from the spikewhen engaging the in clined lower wall of the anchor groove or slot tosecurely anchor the spike in the tie.

A further object of the invention resides in the provision of a spike ofthe above stated character which will also be provided with an anchoringpin constructed in such a manner that it will be prevented from bitinginto the wood until driven into the bottom of the groove of the spikeand turned by the beveled end wall thereof in the proper direction intothe body of the tie, thereby securely anchoring the spike in position.

A further object of the invention resides in the provision of a spike ofthe above stated character which will be of simple construction andinexpensive to manufacture and which will, when driven home, securelyhold the rail in engagement with the tie.

With the above and other objects in view, as will appear as thedescription proceeds, the invention consists in the novel construction,combination and arrangement of co- A pplication filed June 29,

operating elementsas hereinafter more specifically set forth, claimedand shown in the accompanying drawings, in which:

Figure 1 is a section through a portionof atie and rail mounted thereonwith the improved spike in use, the head of the anchor pin being shownin positionand dotted lines also being employed in this view to showthemanner in which the head of the anchor 7 pin may be bent away from thespike for the purpose of engaging a tool with the anchor pin to removethe same.

Figure 2 isa plan view of the spike looking at the head thereof.

'Figure 3 is a rear view, showing the position and form of the slot orgroove for the anchor pin.

Figure 4 is a longitudinal detail section through the device, taken onthe line l4t of Figure 3;

Figure 5 is a detail view of the anchor pin.

Referringmore in detail to the drawings, in which similar referencecharacters designate corresponding parts throughout the several views,1' designates the spike which may be driven in the usual manner in thetie 2 with the nose or extended front portion 3 of the spike'head 4tengaged with'the upper face of the lower flange 5 of the rail base tosecurely clamp the rail in position upon the tie. The spike 1 isprovided with the free or driving end 7 pointed by beveling the oppositefaces 8 of the shank of the spike 1 to facilitate driving of the same inthe tie 2.

The slot or groove 9 is provided in the spike 1 and extends from thehead 4;, opening on the outer or upper face thereof, to a point abovethe longitudinal center of the shank of the spike 1, as clearly shown inFigures 1, 3 and a, the lower wall 10 of the groove or slot 9 beingbeveled and rounded, as shown in Figures 3 and a, and the purpose ofwhich will presently appear. The groove or slot 9 is formed in the rearor outer side of the spike and opens upon the rear face of the spikethroughout the entire length of the groove or slot 9. r

In order to securely anchor the spike in the tie 2, an anchor pin 11 isprovided which conforms to the shape of the groove or slot 9 but has alength greater than the length of the groove or slot 9, a flattened head12 being formed on the upper end of the body or shank of the anchor pin11 while the lower end of the shank is beveled on one face, as shown at13, for engagement with the lower wall 10 of the slot or groove 9 toturn the end of the anchor pin 11 away from the spike 1 as the anchorpin 11 is driven home, the sharp edge it provided by bevellin-g the endof the anchor pin shank, permitting the pin to be readily forced intothe tie 2 at an angle to the slot or groove 9, as shown in Figure 1.

It will alsobe noted by referring particularly to Figure 5 of thedrawings that the anchor pin 11 is tapered or beveled on its rear sidefrom a point below the longitudinal center of the anchor pin to thebeveled lower end thereof to prevent the lower end of the spike frombiting into or becoming caught in the fiber of the tie while beingdriven into the slot 9 of the spike 1.

From the foregoing, taken in connection with the drawings, it will beevident that after the spike 1 has been driven home, the anchor pin 11may be driven into the slot or groove .9 without danger of the anchorpin entering into or tea-ring the fibers of,

the tie 2 until the lower beveled end 18 of the anchor pin engages theinclined or beveled wall 10 of the slot or groove 9 when the point 14 ofthe anchor pin 11 will be directed outwardly away from the spike l andinto the fibers of the tie 2 at an inclined angle, as shown by dottedlines in F i-gure 1 of the drawings. The angle at which, the lower endof the anchor pin 11 enters the tie 2 will correspond to the inclinationof the wall 10, as will be evident, thereby causing the anchor pin 11 tosecurely anchor the spike 1 in position within the tie 2. The beveled ortapered side of the anchor pin 11 has been designated by the numeral11'.

Then it is desired to remove the spike 1, it is simply necessary to bendthe anchor pin 11 away from the head 4 of the spike 1 as shown by dottedlines in Figure 1 o the drawings, after which a suitable tool may beengaged with the head 12 of the anchor pin 11 and the anchor pin 11readily withdrawn, after which the spike 1 may be removed from the tie2.

While the preferred embodiment of the invention has been shown anddescribed, it will be understood that minor changes in the details ofconstruction and arrangement of parts may be resorted to within thescope of the appended claim without departing from the spirit of theinvention.

What is claimed is A spike having a substantially longitudi nallydisposed groove in a side wall thereof, and a deflecting surface at thebase of said groove, an anchoring pin for insertion into said groove,said pin having a deflected surface at its lower end for cooperationwith said surface to deflect the lower end of said pin into the elementreceiving the spike, said pin being provided with a bevelled sur faceextending from the opposite side of the spike to its deflected endaforesaid in order to prevent engagement of the lower end of the pinwith said element until deflected thereinto through coaction of thedeflecting surface.

In testimony whereof I aflixmy signature in presence of two witnesses.
